Commentary Par VI 92-93

'Titus, son and successor of Vespasian, Roman emperor, A.D. 79-81; he served under his father in the Jewish wars, and when Vespasian was proclaimed emperor and returned to Italy in 70 he remained in Palestine in order to carry on the siege of Jerusalem, which he captured, after a siege of several months, in September of that year; in the following year he returned to Rome and celebrated the conquest of the Jews in a triumph with his father' (Tito).  For a clear explanation of this tercet, see Tozer (DDP Tozer.Par.VI.91-93): 'The repetition is that of the word vendetta in two different applications, corresponding to the twofold mission of the eagle; first it avenged God's wrath against Adam's sin (vendetta del peccato antico) by putting Christ to death; then it took vengeance on the Jews for bringing about Christ's death by the destruction of Jerusalem by Titus.'

Giorgio Padoan (Pado.1965.2), pp. 7-17, looks away from the canto of his Lectura Dantis Romana (Par. VII) to consider these verses and their problematic view of Jewish history.
